Recommendations
- • Increase HSTS max-age to at least 1 year and add includeSubDomains
- • Improve CSP by adding more specific directives and removing 'unsafe-inline'
- • Add Referrer-Policy header (recommended: strict-origin-when-cross-origin)

Recommendations
- • Consider using critical flag (flags=128) for stricter CAA enforcement
- • You have authorized 5 CAs - consider limiting to only the CAs you actively use
- • Consider adding 'iodef' records to receive notifications about unauthorized certificate issuance attempts
